APRSD is a python application for interacting with the APRS network and providing APRS services for HAM radio operators.
- APRSD currently has 4 main commands to use.
- server - Connect to APRS and listen/respond to APRS messages
- webchat - web based chat program over APRS
- send-message - Send a message to a callsign via APRS_IS.
- listen - Listen to packets on the APRS-IS Network based on FILTER.
Each of those commands can connect to the APRS-IS network if internet connectivity is available. If internet is not available, then APRS can be configured to talk to a TCP KISS TNC for radio connectivity.
Please read the docs to learn more!
APRSD's typical use case is that of providing an APRS wide service to all HAM radio operators. For example the callsign 'REPEAT' on the APRS network is actually an instance of APRSD that can provide a list of HAM repeaters in the area of the callsign that sent the message.
Ham radio operator using an APRS enabled HAM radio sends a message to check the weather. An APRS message is sent, and then picked up by APRSD. The APRS packet is decoded, and the message is sent through the list of plugins for processing. For example, the WeatherPlugin picks up the message, fetches the weather for the area around the user who sent the request, and then responds with the weather conditions in that area. Also includes a watch list of HAM callsigns to look out for. The watch list can notify you when a HAM callsign in the list is seen and now available to message on the APRS network.

APRSD has a web admin interface that allows you to view the status of the running APRSD server instance. The web admin interface shows graphs of packet counts, packet types, number of threads running, the latest packets sent and received, and the status of each of the plugins that are loaded. You can also view the logfile and view the raw APRSD configuration file.
To start the web admin interface, You have to install gunicorn in your virtualenv that already has aprsd installed.
source <path to APRSD's virtualenv>/bin/activate aprsd admin --loglevel INFO
The web admin interface will be running on port 8080 on the local machine. http://localhost:8080
git clone git@github.com:craigerl/aprsd.gitcd aprsdmake
While working aprsd, The workflow is as follows:
Checkout a new branch to work on by running
git checkout -b mybranchMake your changes to the code
Run Tox with the following options:
tox -epep8tox -efmttox -p
Commit your changes. This will run the pre-commit hooks which does checks too
git commitOnce you are done with all of your commits, then push up the branch to github with:
git push -u origin mybranchCreate a pull request from your branch so github tests can run and we can do a code review.
To do release to pypi:
Tag release with:
git tag -v1.XX -m "New release"Push release tag:
git push origin master --tagsDo a test build and verify build is valid by running:
make buildOnce twine is happy, upload release to pypi:
make upload
APRSD plugins are the mechanism by which APRSD can respond to APRS Messages. The plugins are loaded at server startup and can also be loaded at listen startup. When a packet is received by APRSD, it is passed to each of the plugins in the order they were registered in the config file. The plugins can then decide what to do with the packet. When a plugin is called, it is passed a APRSD Packet object. The plugin can then do something with the packet and return a reply message if desired. If a plugin does not want to reply to the packet, it can just return None. When a plugin does return a reply message, APRSD will send the reply message to the appropriate destination.
For example, when a 'ping' message is received, the PingPlugin will return a reply message of 'pong'. When APRSD receives the 'pong' message, it will be sent back to the original caller of the ping message.
APRSD plugins are simply python packages that can be installed from pypi.org. They are installed into the aprsd virtualenv and can be imported by APRSD at runtime. The plugins are registered in the config file and loaded at startup of the aprsd server command or the aprsd listen command.
You can build your own plugins by following the instructions in the Building your own APRSD plugins section.
Plugins are called by APRSD when packe
There are 2 versions of the container Dockerfile that can be used. The main Dockerfile, which is for building the official release container based off of the pip install version of aprsd and the Dockerfile-dev, which is used for building a container based off of a git branch of the repo.
docker build -t hemna6969/aprsd:latest .
docker build -t hemna6969/aprsd:latest -f Dockerfile-dev .
There is a docker-compose.yml file in the docker/ directory
that can be used to run your container. To provide the container
an aprsd.conf configuration file, change your
docker-compose.yml as shown below:
volumes:
- $HOME/.config/aprsd:/config
To install plugins at container start time, pass in a list of
comma-separated list of plugins on PyPI using the APRSD_PLUGINS
environment variable in the docker-compose.yml file. Note that
version constraints may also be provided. For example:
environment:
- APRSD_PLUGINS=aprsd-slack-plugin>=1.0.2,aprsd-twitter-plugin
